To all 10700711 it may concern Be it known that ROBERT F IOLA, a citizenof the United States, residing at Dayton, in the county of Montgomeryand State of Ohio, has invented certain new and useful Improvements inW'indows, of which the following is a specification.

This invention relates broadly to windows and has for its primary objectto provide an improved window structure whereinthe slidable sashesthereof are capable, when closed, of assuming positions in true verticalalignment, so that a neat andtinished appearance thereof may beeffected, together with utilitarian advantage of providing closeregistration between the joints of the sashes in order that the weathermay be effectively excluded.

The invention accordingly consists in the provision of a windowstructure wherein the lower sash is provided with an improved pivotalmounting, the same serving, when the sash is in its extreme loweredposition, to permit the sash to be laterally shifted, whereby the sameis capable of being positioned immediately under and in verticalregistration with the upper sash and to prevent undue sliding movementthereof.

Another object of the invention resides in the provision of means forsecurely locking the sashes in assembled relationship and in theprovision of supplemental means for the purpose of preventingunauthorized actuation of the lower sash.

With these and other objects in view, as will appear as the descriptionproceeds, the invention accordingly consists in the novel features ofconstruction, combinations of elements and arrangement of parts,hereinafter to be fully described and to have the scope thereof pointedout in the appended claims. i

in the accompanying drawings, forming a part of this specification, andin which similar characters of reference denote like and correspondingparts: a

Referring more particularly to the structural details of the invention,use is made of a window frame 1. This frame is constructed to embodyvertically extending and spaced side bars 2 with which casings 3 areconnected, the interiors of the latter being formed to define weightreceiving chambers 1. Thebars 2 have connected with the inner facesthereof vertically extending guide strips 5, 6 and 7 which are adaptedto slidably receive the upper and lower sash members 8 and 9respectively of thewindow. These sash members are formed to embodytheusual marginal bars 10, which support the transparent panels 11.

In this instance. the upper sash member is slidably received between theintermediate and outer guide strips 6 and '7 respectively so that themovement thereof may be, ef fected in the customary manner. To seal thejoints between the upper sash and the frame 1, said sash has its upperbar 12 longitudinally grooved as at 13, whereby when the sash occupiesits extreme upper position, the groove '13 will receive a longitudinallyextending head 14 provided upon a weather strip 15. This constructionmerely tends to exclude the entrance of the elements. The side edges ofthe upper sash member are firmly retained between the guide strips 6 andi" so that the vertical edges of the sash will alsobe protectedagainstthe undue entrance of weather. a

To raise and lower the upper sash in a convenient manner, the lowercorner edges thereof are connected with cables 16, and these cablesextend vertically upward in grooves 17 provided in the sidebars 2, saidcables extending contiguous to the side edges of'the upper sash member."The cables 16 are then trained in the usual manner over guide pulleys18, shown in Figure 8, and the cable on the left of this sash passeshori- 'zontally across the window frame in the pulley chamber 19provided therefor. I The free ends of said cables after passing aroundthe pulleys, project downwardly into the chamber a, and are securelyconnected with a weight 20 slidably mounted therein. The weight acts inthe usual manner to counterbalance the weight of the upper sash member8, and to permit of its free and convenient actuation. By'connecting thecables 16 with the lower corner edges of said sash member, convenienceand facility are to be obtainedin effecting the sliding movements of thesash member, as the construction merely tends to reduce binding or unduefriction between parts.

The. lower sash member is similar in construction and operation to theupper sash member and is of such form as to be capable of beingpositioned in vertical alignment with the upper sash member when bothsashes occupy closed positions. To this end, the lower sash member isadapted to be slidably received between the inner and intermediate guidestrips 5 and 6 respectively. However,these strips terminate centrally ofthe window frame, thus permitting said lower sash member to be laterallyshifted when the same is lowered. To effect the support and operation ofthe lower sash member, the sidebars 2 are further grooved as at 21, andreceive cables 22, which correspond in construction and utility to theupper sash cables 16. In this instance, the cables22 have their lowerends, as shown in Figure 7,.se'cured to a pair of cable attachingmembers 23 which are also slidably received within the grooves 21. Theattaching members embody headed studs 24 which project toward the lowersash member. These studs are adapted to receive the bifurcated ends 25of a pair of pivot arms 26, which are pivotally carried as at 27 uponthe lower corner edges of the lower sash member.

- Further, the arms 26 are formed to include rigidly mounted andinwardly extending pins 28, whereby when the lower sash member occupiesits position in alignment with the space between strips 5 and 6, saidpins 28 will be positioned within recesses or sockets 29, formed in saidlower sash member. This construction is clearly disclosed in Figure 6.By yirtue thereof, it will be manifest that the weight of the lower sashmemher is directly received by the arms 26, and that the latter, inturn, are supported and carried by the lower ends of the cables 22.

,Therefore, said cables serve to support the lower sash member and thissupport is effected from the lower corner edges thereof. The cables 22pass vertically upward through the grooves'2l, and are trained overpulleys provided in the chamber 19. From these pulleys, the free ends ofthe cables 22 depend downwardly and are attached tothe"counterbalancing.weight 31, which is slidably received, as is theweight 20, in the chamber 4. By virtue of this construction, themovements of either of the sash members may be quickly and easilyaccomplished without undue friction or bindmg, p v

7 As shown-in Figure5, the bottoms of the side bars 2- aresuitably-morticed to receive catch brackets 32. These brackets areprovided with substantially U shaped slots 33, the inner of which aredesigned to receive the shanks of the studs 24. Thus, when the lowersash assumes its closed position,.the studs 24-. will be positioned inthe blind extremities of the slots 33, so that one attempting to raisethe window by a direct upward thrust will be frustrated in the attempt.However, to-raise the window, it is simply necessary to force the sameinwardly so that the studs 24 will be positioned in the open extremitiesof the slots 33 which are of course locatedin registration with thegrooves 21. In this manner, one having knowledge of the operation of thewindow may conveniently effect its raising and lowering; however, itssurreptitious operation by unauthorized persons is rendered a matter ofsome complexity.

To register the sash members, the lower sash member is movedlaterally byoscillating the arms 26 abouttheir stud pivots 24: so that the lowergroove bar 34 of the lower sash'member may be placed upon a beadedweather strip carried upon the lower bar of the window frame. Then, byusing this latter-bar in the capacity of a fulcrum, the upper edge ofthe lower sash may be oscillated outwardly until the upper bar 36thereof comes into contact with the lower bar 37 ofthe upper sashmember. This relationship betweenparts may be maintained. by providingthe bar 36 with a socket 38, in which is pivotally mounted a catchfinger 39. By rotatingthis finger, the same may be forced into a pocket40 formed in the bar I of the-sash members, so that the latter will be'lirmly retained in their assembled and registering positions. Ifdesired, the operating shaft .41 of the finger 39 may be provided with apinion 42, clearly disclosed in Figure 9. This pinion is adapted toengage with a. plurality of rack teeth a?) provided upon the ends oflocking rods L4. These rods are adapted to be slidably received withingrooves 45 formed in the upper bar 36, and the ends of the rodsterminate in contiguous relationship with the side bars 2. Obviously,upon rotating the finger 39 so as to position the latter within thepocket 40, said pinion 42 will also be rotated. This rotation of thepinion will cause outward movement on the part of the rods as, so thatthe latter will be forced into frictional engagement with. the sides ofthe bars 2, and in this manner the sashes will be firmly locked inposition so as to prevent rattling and unauthorized actuation. The rods44, however, are primarily provided for the purpose of retaining thelower sash member in a secure manner when in its lower position inasmuchas the latter is then without the support of the guide strips 5 and 6. Aknob 41 is provided on the outer end of the shaft $1 to facilitatemanipulation of said shaft. 1

In operation, when it is desired to elevate the lower sash member, theshaft 41 is rotated so that the finger 39 will be released fromengagement with the upper sash member, and this action alsosimultaneously results in the release of the rods I A from their lockingcooperation with the bars 2. When this release is effected, the upperedge of the lower sash member is oscillated in an inward direction, orin other words, away from the upper sash member, this movement takingplace with the weather strip 35 as a pivot, and this inward movement ofthe lower sash member is limited by the contacting of its upper edge, asshown in Figure 4, with the inner strips 5. Then, to release the loweredge of the sash mem ber 9. the latter is slightly elevated so that thesame will be clear of the strip 35. This slight elevation is permittedby virtue of the relative play between the links 26 and the attachingmembers 23. Obviously, when dear of the weather strip 35, the lower sashmember as a whole may be bodily moved so as to align itself with theguides formed between the strips 5 and 6. It will of course beappreciated that during this latter movement, the lower sash member ispivotally supported upon the studs 24 and its movement is guidedthereby. Then, to limit the inward movement of the member 9, the pins 28will. contact with the inner walls of the recesses 29 so that furtheroutward movement will be prevented. Then, by lowering the member 9, thestuds 24 may be forced out of engagement with the blind ends of theslots33 and positioned in the open extremities thereof, so that by theapplication of upward pressure, said sash member 9 may be caused totravelin its ordinary manner between the guide strips 5 and 6. Thisoperation is of course reversible when it is desired to locate the lowersash member in vertical alignment and positive engagement with the uppersash member. The outer of the brackets 32 are slotted in a mannersimilar to the inner brackets. These outer brackets are adapted toreceive studs 46 formed upon the lower corner edges of the upper sashmember and with which the lower ends of the cables 16 are attached.Obviously, when the upper sash member assumes its extreme lowerposition, the studs 46 will project into the U shaped slots of the outerbrackets 32 and will have a tendency to lie in the blind extremitiesthereof. This construction prevents the raising of the upper sash memberby direct pull and therefore necessitates a lateral thrust so as toclear the studs 4C6 of the blind extremities of said slots and toposition the same in the open extremities. When this is accomplished,the direct upward thrust will then result in the raising of the window.In other words, the provision of the outer brackets provides anautomatic lock for the upper sash member when the latter is in itslowered position.

From the foregoing description, taken in conjunction with theaccompanying sheets of drawing, it will be apparent that the presentinvention provides an improved sash structure wherein the sashes arecapable of being brought and maintained in vertical. alignment andregistration, so that a neat and attractive appearance will be securedand the entrance of weather effec tively precluded. The invention alsocombines the improved pivotal mounting for effecting the support of thelower sash member, said mounting permitting of a lateral movement on thepart of the lower sash member when the latter assumes its closedposition. By connecting the cables with the lower ends of the sashmembers, facility is to be had in the raising andlowering and theelement of binding wholly eliminated.

I claim:

1. In a window structure, a frame, a pair of sash members slidablyreceivedwithin said frame, means whereby the lower of said sash membersmay be brought .into and out of vertical registration with the upper ofsaid sash members, comprising a pair of pivot arms pivotally carried bythe side edges of said lower sash member, studs connected with said armsopposite to the points of connection of the latter with said lower sashmember. said studs constituting pivot supports for said arms, a weightcarrying cable structure. connected with said studs,
